The NPX Screen prevents NPX Bioplastics or other biodegradable pelletized media from passing through the dispersion plates in the Phosban Reactor 150 or Phosban Reactor 550.

NPX screens are to be used instead of the foam sponges in the Phosban reactors. Remove the sponge and position the cut screen on top of the dispersion plates. Normally the screens will fit snugly in place if they are cut correctly, but small plastic zip ties can also be used to secure them to the dispersion plates.
